Ten kod zadziałał dla mnie,
MediaPlayer mp = MediaPlayer.create(context, R.raw.sound_file_1);
mp.start();
Dla Niemy
mp.setVolume(0,0);
& Unmute lub full volume
mp.setVolume(1,1);

AudioManager mAudioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
int current_volume =mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
//If you want to player is mute ,then set_volume variable is zero.Otherwise you may supply some value.
int set_volume=0;
mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC,set_volume, 0);

Możesz chcieć wyciszyć / wyciszyć dźwięk, zamiast natychmiast ustawić go na pełną (1.0 f) lub zerową (0.0 f) głośność.
Jest to trochę trudne, ponieważ potrzebujesz zadania asynchronicznego, aby Twoja aplikacja była responsywna:MpMain jest moją instancją MediaPlayer do odtwarzania zapętlonej muzyki w tle. Zależy mi również na OnPause () i OnResume ().
Metoda playBackgroundMusic służy do włączania muzyki, fadeOutBackgroundMusic wyłącza muzykę, ale przez zanik głośności na 0,5 sekundy (10*50, patrz while I wątek.snu).Mój base-volume to 0.8 f, możesz zrobić z tego parametr zadania asynchronicznego lub użyć statycznej zmiennej globalnej.
public void playBackgroundMusic( Boolean isOn ){
if(isOn){
// prevent conflics with async fade-out task
if(mtask_fadeout_music!=null){
mtask_fadeout_music.cancel(true);
mtask_fadeout_music=null;
}
if(mpMain==null){
mpMain = MediaPlayer.create(this, R.raw.zin___piano_2_140bpm_32158);
mpMain.setLooping(true);
mpMain.setVolume(0.8f,0.8f);
mpMain.start();
}
}
else{
if(mtask_fadeout_music==null){
fadeOutBackgroundMusic();
}
}
}
public void fadeOutBackgroundMusic(){
mtask_fadeout_music = (FadeOutMusic)new FadeOutMusic( ).execute( );
}
//
// background processing ... fade out music stream
//
public class FadeOutMusic extends AsyncTask<String,Integer,String> {
@Override
protected String doInBackground(String... args) {
float level = 0.8f;
int i = 1;
while(i<50){
i++;
if(mpMain != null){
level=level*0.9f;
mpMain.setVolume(level, level);
}
try {
Thread.sleep(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
return "dummy";
}
@Override
protected void onPostExecute( String dummy ) {
if(mpMain != null){
mpMain.setVolume(0,0);
mpMain.release();
mpMain = null;
}
if(mtask_fadeout_music!=null){
mtask_fadeout_music = null;
}
}
@Override
public void onCancelled() {
if(mpMain != null){
mpMain.setVolume(0,0);
mpMain.release();
mpMain = null;
}
if(mtask_fadeout_music!=null){
mtask_fadeout_music = null;
}
}
}

AudioManger.setStreamMute
jest przestarzały.
użyj poniższego kodu alternatywnego.
AudioManager am = getSystemService(Context.AUDIO_SERVICE);
// Change the stream to your stream of choice.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
am.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_MUTE, 0);
} else {
am.setStreamMute(AudioManager.STREAM_MUSIC, true);
}

Spróbuj tego...
AudioManager manager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
manager.setStreamMute(AudioManager.STREAM_MUSIC, true);

Spróbuj tego
AudioManager am = getSystemService(Context.AUDIO_SERVICE);
// Request audio focus.
am.requestAudioFocus(listener, AudioManager.STREAM_MUSIC,AudioManager.AUDIOFOCUS_GAIN);
